This invention relates to means for yieldingly mounting an automobile engine on its frame and the rincipal ob'ect thereof is to provide a simp e means w ich in addition 6 to forming a universal yielding connection between the engine and its frame also functions as a sound interrupter that prevents the humming sound from the engine while in action from being transmitted to the sup 1 port where the noise is usually amplified much to the annoyance of persons near the en me. r

nother object is to provide a relatively. strong yielding connectlon between the en-' ineand su ort that is simple to make and install and w ich in use can yield slightly in any direction without danger of being disconnected by excessive shock or vibration. To that end I provide relatively strong positely arrange and very rigidly secure to the frame with seats on their inner ends for cylindrical rub ber cushions with transverse ribsfor limiting the movement of the cushions toward the frame. The cushions are provided with tapered sockets into which tapered hubs are loosely and slidably fitted with the hubs secured to the sides of the engineso the latter can have a sli ht universal movement. tapered sockets in the cushions are arranged so that when the vibration of the engine. or shock of travel causes it to move sidewise the hubs on one side of the engine will loosen in their sockets and theother hubs will correspondingly tighten.

e invention is to P I07 Another object of t vide simple means for mounting an engine on a frame so it will be at all points out of metal contact and in floating suspension on the frame, and with the supporting means constructed to Iyl ieldingly resist independent movement of t e engine and frame relativ to each other in every direction.

A feature of invention is shown in the means for seating the sound and vibration insulating cushion.

Other objects, advantages and features of invention may a pear from the accompanying drawing, t e subjoined detailed de- "scription and appended claims.

The accompanying drawing illustrates the 1nvent1on,in which:

Figure 1 is a fra mental cross section through one side of t e automobile frame showing a side view fragmental planview of an automobile frame-showing an internal combust1on engine connected to the frame by of one of my cushion supports connecting one side of an engine to the frame. F1 3 is a section on line 3-3 of Fig. 2 on a sli Etly smaller scale. I Fi .4 is an enlarged ragmental sectionon ine 44, Fig. 1, showing the detailed construction of one of my cushion supports, parts drawn to the same scale as those shown in Fig. 2; also showi that the engine is supported entirely out 0 metal contact with t e frame. Fig. 5 is a section on line 55, Fig. 2, with parts drawn to the same scale as Fig. 3. Fig. 6 isa-perspective view of the resilient soundv .and vibration interrupting cylindrical rubber block used in my engine support showing the end socket'for receiving the hub of the support and also the recesses for receiving the bolt heads that secure the hub baseplate to the engine. Fi 7 is a section on line 77, Fig. 4, on a shghtly smaller scale showing the concave block seat for the sound interrupter rubber block. I

In detail the engine su port 10 includes a bracket 11, hub 12, cylin rical rubber block 13 and strap 14 that are constructed, assembled, installed and used as illustrated in the accompanying drawing, and is made in various sizes suitable for supporting any size or make of engine, whether it is used in an automobile, boat or airplane frame. Also the engine support can be used in sets of two, three four or more.

As illustrated by engine 15 is su ported on the frame 16 by full lines in Fig. 1, the 1 dotted lines an engine.

so the engine'will be supported at three places instead of four, as

shown by full lines.

' ed at right angles thereto is a concave block plate 19 that at its outer end has oppositely extending lugs 20 that rest on the lower flange of the channel iron of frame 16 to reinforce the bracket and aid in holding it in fixed position in the frame.

A stop rib 21 extends transversely across the inside of the concave block seat 19 and is integral therewith and arranged to limit the outward movement of the cylindrical rubber block 13 that is seated in the end of the transversely concave block seat and secured thereon by the strap 14 that is secured by bolts'22 to the oppositely extending clamp lugs 23 that are integral with the block seat 19.

The tapered hub 12 is adapted to be fitted snugly into a socket 24 extended centrally into an end of the rubber cushion 13, and the hub is provided with an integral baseplate' 25 that is adapted to be secured by bolt 26 to a side of the engine 15, and the rubber cushion 13 is recessed at 2'! to form clearances for the heads of the bolts 26. The rubber block 13 is extended over the inner end of the concave block seat 19 to aid in holding the engine 15 entirely out of metal contact with the bracket 11 and also toadd resiliency to the connection between theengine and frame. llt is understood that there can be two or more of thebolts 26 or a number suilicient to safely support the weight of the engine under all operating conditions. 'llhe outer end portion of the cylindrical rubber block 13 is solid as best shown in Fig. 4, and the outer end of the hub 12 engages this solid end portion centrally so that when there is a side thrust to the engine the force thereof will be applied both to the inner end of the block and on its solid end portion.

Preferably I employ four of my engine supports for each engine arranged adjacent the four corners to distribute the weight equally between them, as shown by full lines in Fig. 1, but it is understood that with very light weight engines It may employ only three supports, as previously indicated, and with heavy engines I can employ as many as are necessary.

' In operation the parts of the engine supports are assembled and installed as shown and described and when so attached to the engine and frame form a floating suspension of the engine, and permit a yielding resisting movement between the frame and engine that is universal relative to the direction in which it is imparted, and this yielding resistance prevents injury or excessive shock or vibrational wear to the engine and frame or to their connecting supports. That is,- the engine and frame while being very securely connected by my supports are held entirely out of metal contact by the cylindrical rubber blocks interposed between them, and the blocks are made exceptionally large relative to the other parts of the supports so the engine can have considerable play by the yielding'of the blocks when it is subjected to heavy shock incident to automobile travel.

I claim as my invention: a

1. A yielding'support for an engine including a frame, a bracket secured to said frame, a concave seat extended inwardly from said frame, a cylindrical rubber block on said seat having a compact outer end portion and a tapered socketextending inwardly from its inner end, an engine, a tapered hub secured to the side of said engine and loosely fitted into the socket of said rubber block,

and a strap for securing said block to said seat, said rubber block having its socket end extended inwardly beyond the inner end of said concave seat to hold said engine out of metal contact with said bracket and frame.

2. A yielding support for an engine in cluding a frame, channel irons thereon an engine arranged between said irons, brackets, secured to said irons, concave block seats integral with said brackets and extended inwardly toward said engine, stops adjacent the outer ends of said seats, cylindrical rubber blocks on said seats having tapered sockets extending inwardly from the inner ends of said blocks and the solid outer ends of said blocks engaging said stops, tapered hubs secured toithe sides oi said engine and loosely extended into the sockets of said blocks, and straps for securing said blocks in said seats, said blocks extending over the inner ends of said seats and other parts arranged to hold said engine out of metal contact with said bracltet and frame and permit universal movement on said yielding supports to compensate for shocks incident to automobile travel.

In witness whereof I have hereunto afixed my signature.
